also I have noticed what was my problem , I had to write this in PHP.ini :

doc_root =

leave it blank , and not to write :

doc_root ="C:\Inetpub\wwwroot\"

as written in all guides

now I have some question about sessiondata and uploadtemp directories.
because I used the ZIP file installation of PHP then those directories were not created automatically , so I had to creat them manually.
but the big question is were I have to tell PHP to use those directories because up to now it doesn't make usuage of those directories.

also now , after finished to install PHP on the server , I have now to setup (install) PHP extensions.

may you suggest me which PHP extensions I have to install ?

also , when I enter to PHPmyAdmin I get this error :

The mbstring PHP extension was not found and you seem to be using multibyte charset. Without mbstring extension phpMyAdmin is unable to split strings correctly and it may result in unexpected results

so as I understand that I first need to install mbstring PHP extension.
but the problem is that when I enable the mbstring on PHP.ini then IIS 6 is crashing (stop to work)

in event Viewer I get this error :

The registry key for IIS subauthenticator is not configured correctly on local machine, the anonymous password sync feature is disabled.

How I installed the mbstring in PHP.ini ?
I just deleted the ; before extension=php_mbstring.dll
so now it looks like this:
extension=php_mbstring.dll

now i want to show you my PHP.ini file :

[PHP]

;;;;;;;;;;;;;;;;;;;
; About this file ;
;;;;;;;;;;;;;;;;;;;
;
; This is the recommended, PHP 4-style version of the php.ini-dist file. It
; sets some non standard settings, that make PHP more efficient, more secure,
; and encourage cleaner coding.
; The price is that with these settings, PHP may be incompatible with some
; applications, and sometimes, more difficult to develop with. Using this
; file is warmly recommended for production sites. As all of the changes from
; the standard settings are thoroughly documented, you can go over each one,
; and decide whether you want to use it or not.
;
; For general information about the php.ini file, please consult the php.ini-dist
; file, included in your PHP distribution.
;
; This file is different from the php.ini-dist file in the fact that it features
; different values for several directives, in order to improve performance, while
; possibly breaking compatibility with the standard out-of-the-box behavior of
; PHP 3. Please make sure you read what's different, and modify your scripts
; accordingly, if you decide to use this file instead.
;
; - register_globals = Off [Security, Performance]
; Global variables are no longer registered for input data (POST, GET, cookies,
; environment and other server variables). Instead of using $foo, you must use
; you can use $_REQUEST["foo"] (includes any variable that arrives through the
; request, namely, POST, GET and cookie variables), or use one of the specific
; $_GET["foo"], $_POST["foo"], $_COOKIE["foo"] or $_FILES["foo"], depending
; on where the input originates. Also, you can look at the
; import_request_variables() function.
; Note that register_globals is going to be depracated (i.e., turned off by
; default) in the next version of PHP, because it often leads to security bugs.
; Read http://php.net/manual/en/security.registerglobals.php for further
; information.
; - display_errors = Off [Security]
; With this directive set to off, errors that occur during the execution of
; scripts will no longer be displayed as a part of the script output, and thus,
; will no longer be exposed to remote users. With some errors, the error message
; content may expose information about your script, web server, or database
; server that may be exploitable for hacking. Production sites should have this
; directive set to off.
; - log_errors = On [Security]
; This directive complements the above one. Any errors that occur during the
; execution of your script will be logged (typically, to your server's error log,
; but can be configured in several ways). Along with setting display_errors to off,
; this setup gives you the ability to fully understand what may have gone wrong,
; without exposing any sensitive information to remote users.
; - output_buffering = 4096 [Performance]
; Set a 4KB output buffer. Enabling output buffering typically results in less
; writes, and sometimes less packets sent on the wire, which can often lead to
; better performance. The gain this directive actually yields greatly depends
; on which Web server you're working with, and what kind of scripts you're using.
; - register_argc_argv = Off [Performance]
; Disables registration of the somewhat redundant $argv and $argc global
; variables.
; - magic_quotes_gpc = Off [Performance]
; Input data is no longer escaped with slashes so that it can be sent into
; SQL databases without further manipulation. Instead, you should use the
; function addslashes() on each input element you wish to send to a database.
; - variables_order = "GPCS" [Performance]
; The environment variables are not hashed into the $HTTP_ENV_VARS[]. To access
; environment variables, you can use getenv() instead.
; - error_reporting = E_ALL [Code Cleanliness, Security(?)]
; By default, PHP surpresses errors of type E_NOTICE. These error messages
; are emitted for non-critical errors, but that could be a symptom of a bigger
; problem. Most notably, this will cause error messages about the use
; of uninitialized variables to be displayed.
; - allow_call_time_pass_reference = Off [Code cleanliness]
; It's not possible to decide to force a variable to be passed by reference
; when calling a function. The PHP 4 style to do this is by making the
; function require the relevant argument by reference.

; Output buffering allows you to send header lines (including cookies) even

; buffering functions. You can also enable output buffering for all files by
; setting this directive to On. If you wish to limit the size of the buffer
; to a certain size - you can use a maximum number of bytes instead of 'On', as
; a value for this directive (e.g., output_buffering=4096).

; Note: People who wrote portable scripts should not depend on this ini
; directive. Instead, explicitly set the output handler using ob_start().
; Using this ini directive may cause problems unless you know what script
